    gdbus-test-codegen: Cast to void* to printf "%p"
    
    to suppress a compiler error with stricter warnings enabled (GCC):
    
    gdbus-test-codegen.c: In function ‘on_handle_get_self’:
    gdbus-test-codegen.c:403:26: error: format ‘%p’ expects argument of type
     ‘void *’, but argument 2 has type ‘GThread * {aka struct _GThread *}’
     [-Werror=format=]
       s = g_strdup_printf ("%p", g_thread_self ());
